Register a component-scoped shortcut

Worked example: adding a n shortcut on the Projects index page that opens the "new project" flow — scoped to that page, unlike ctrl+k which should work everywhere (see 02-register-a-global-shortcut.md for that shape instead). This mirrors Sidebar.tsx's real p → "Create project" shortcut exactly.

The key string format

Always lowercase — ShortcutContext normalizes both the registered key and the pressed combination to lowercase before comparing, so 'Ctrl+K' and 'ctrl+k' behave identically, but write it lowercase for consistency with every existing definition.

Step — Register the shortcut with useShortcuts()

File: resources/js/Pages/Projects/Index.tsx

import { useShortcuts } from '@/context/ShortcutContext';
import { ShortcutDefinition } from '@/types/Shortcuts';
import { useMemo, useState } from 'react';

export default function ProjectsIndex({ projects }: ProjectsIndexProps) {
    const [isNewProjectModalOpen, setIsNewProjectModalOpen] = useState(false);

    const shortcuts = useMemo(
        (): ShortcutDefinition[] => [
            {
                key: 'n',
                description: 'New project',
                category: 'Creation',
                action: () => setIsNewProjectModalOpen(true),
            },
        ],
        [],
    );

    useShortcuts(shortcuts);

    // ...rest of the component...
}

useMemo here isn't optional decoration — useShortcuts()'s internal useEffect re-registers (unregister the old array, register the new one) whenever the definitions array reference changes, and a fresh [] literal on every render would otherwise unregister/re-register on every single render of the page. If the shortcut's action needs to close over changing state, put that state in the useMemo dependency array rather than dropping the memoization — see Sidebar.tsx's own shortcuts useMemo (empty deps, since its action only calls a stable setState function) for the baseline shape to copy.

Registration/cleanup is automatic: useShortcuts() registers on mount and unregisters on unmount (or whenever definitions changes) via its own internal useEffect — there's no manual cleanup to write at the call site, unlike calling register()/registerBatch() directly (which guide 2 does, since it needs to run once at the provider level, not per-component).

category: 'Creation' places it in the matching section of the help modal, alongside every other 'Creation'-categoried shortcut — pick from the existing ShortcutDefinition['category'] union ('Navigation' | 'Creation' | 'Search' | 'View' | 'Action') rather than inventing a new one unless the shortcut genuinely doesn't fit any existing category.

Tests

• resources/js/context/ShortcutContext.test.tsx — no change needed for a new call site; it already covers register()/useShortcuts() generically, including the actual keydown-matching logic.
• Whichever test covers Pages/Projects/Index.tsx (create one if it doesn't exist) — don't simulate a real keydown event; mock useShortcuts instead and assert against the definitions array it was called with, exactly the pattern resources/js/Components/Organisms/Sidebar/Sidebar.test.tsx's 'registers a "p" shortcut that opens the new project modal' test already uses for its own shortcut:

  const mockUseShortcuts = vi.hoisted(() => vi.fn());
  
  vi.mock('@/context/ShortcutContext', () => ({
      useShortcuts: mockUseShortcuts,
  }));
  
  test('registers an "n" shortcut that opens the new project modal', () => {
      render(<ProjectsIndex projects={[]} />);
  
      const shortcuts = mockUseShortcuts.mock.calls[0][0];
      const newProjectShortcut = shortcuts.find(
          (s: { key: string }) => s.key === 'n',
      );
      expect(newProjectShortcut).toBeDefined();
  
      act(() => {
          newProjectShortcut.action();
      });
  
      expect(screen.getByTestId('new-project-modal')).toBeInTheDocument();
  });
  

  This tests that the component registers the right definition and that its action does the right thing — it deliberately doesn't re-test ShortcutContext's own key-matching/normalization logic, which ShortcutContext.test.tsx already owns.
